What does STAI stand for? 

Stai

The State-Trait Anxiety Inventory (STAI) is a psychological inventory consisting of 40 self-report items on a 4-point Likert scale. The STAI measures two types of anxiety – state anxiety and trait anxiety. Higher scores are positively correlated with higher levels of anxiety. Its most current revision is Form Y and it is offered in more than 40 languages.The STAI was developed by psychologists Charles Spielberger, R.L. Gorsuch, and R.E. Lushene. Their goal in creating the inventory was to create a set of questions that could be applied towards differentiating between the temporary condition of "state anxiety" and the more general and long-standing quality of "trait anxiety." This was a new development because all other questionnaires focused on one type of anxiety at the time.Spielberger also created other self-report state-trait scales purported to measure various other emotions and dispositions. These include the State-Trait Anger Scale (STAS) and the State-Trait Anger Expression Inventory (STAXI). Alternate forms of the STAI have been developed, including a short-form version (STAI-6) as well as a child form, the State-Trait Anxiety Inventory for Children (STAIC).The STAI requires a sixth grade reading level. It is used to aid diagnosis in clinical and other medical settings, including the differential diagnosis of anxiety and depression.
